Barbacena's air quality reflects the Minas Gerais southern plateau at 1,116 metres, with vehicle emissions from the BR-040 and surrounding dairy and healthcare industry contributing local sources. The elevated Serra da Mantiqueira position aids background dispersal, while dry season burning from surrounding Minas Gerais agricultural land contributes seasonal PM2.5 variation throughout the year.

Is air quality bad in Barbacena right now?
On 9 August 2026, overall air quality in Barbacena is good. AQI is the main air quality indicator at 19.5/100. Pollution peaks around 7:00 AM (O3: 19.5/100).

When is air pollution at its worst in Barbacena?
In Barbacena, reduced air quality is most noticeable when native cerrado and Atlantic Forest species pollen peaks, and on days affected by vehicle emissions from the BR-040 and surrounding dairy and healthcare industry; the picture usually improves again once the season turns.
Are air quality levels in Barbacena based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
